Ubuntu Security Notice 6110-1 - It was discovered that Jhead did not properly handle certain crafted Canon images when processing them. An attacker could possibly use this issue to crash Jhead, resulting in a denial of service. It was discovered that Jhead did not properly handle certain crafted images when printing Canon-specific information. An attacker could possibly use this issue to crash Jhead, resulting in a denial of service. It was discovered that Jhead did not properly handle certain crafted images when removing unknown sections. An attacker could possibly use this issue to crash Jhead, resulting in a denial of service.

Ubuntu Security Notice 6097-1 - It was discovered that Linux PTP did not properly perform a length check when forwarding a PTP message between ports. A remote attacker could possibly use this issue to access sensitive information, execute arbitrary code, or cause a denial of service.

Yank Note (YN) 3.52.1 allows execution of arbitrary code when a crafted file is opened, e.g., via nodeRequire('child_process').

BLF file parser crash in Wireshark 4.0.0 to 4.0.5 and 3.6.0 to 3.6.13 allows denial of service via crafted capture file

GDSDB infinite loop in Wireshark 4.0.0 to 4.0.5 and 3.6.0 to 3.6.13 allows denial of service via packet injection or crafted capture file

BLF file parser crash in Wireshark 4.0.0 to 4.0.5 and 3.6.0 to 3.6.13 allows denial of service via crafted capture file

mp4v2 v2.1.2 was discovered to contain a memory leak via the class MP4BytesProperty.

Ubuntu Security Notice 6109-1 - Zheng Wang discovered that the Intel i915 graphics driver in the Linux kernel did not properly handle certain error conditions, leading to a double-free. A local attacker could possibly use this to cause a denial of service. Jordy Zomer and Alexandra Sandulescu discovered that the Linux kernel did not properly implement speculative execution barriers in usercopy functions in certain situations. A local attacker could use this to expose sensitive information.

Ubuntu Security Notice 6054-2 - USN-6054-1 fixed a vulnerability in Django. This update provides the corresponding update for Ubuntu 14.04 ESM and Ubuntu 16.04 ESM. Moataz Al-Sharida and nawaik discovered that Django incorrectly handled uploading multiple files using one form field. A remote attacker could possibly use this issue to bypass certain validations.

A heap-based buffer overflow issue was discovered in libjpeg-turbo in h2v2_merged_upsample_internal() function of jdmrgext.c file. The vulnerability can only be exploited with 12-bit data precision for which the range of the sample data type exceeds the valid sample range, hence, an attacker could craft a 12-bit lossless JPEG image that contains out-of-range 12-bit samples. An application attempting to decompress such image using merged upsampling would lead to segmentation fault or buffer overflows, causing an application to crash.
